How to love a broken and lost spouse

A broken and lost spouse is one who has lost his/her way and resigned from life, perhaps because of being fired from work, retrenchment, trying hard to find a job but nothing coming through, miscarriage (people deal with the loss of a child differently), betrayal by parents and friends, unfair treatment at the work place or place of worship, mid-life crisis, recurring past wounds such as rape, feelings of being a failure due to unfulfilled goals and dreams, emptiness brought about by sacrificing once dreams for the children (this happens a lot with wives), illness or an accident that takes them many steps back.
